How to build a financial due diligence checklist in Excel

Financial due diligence can involve dozens, or even hundreds, of document requests across financial statements, debt, tax, cash flow, and other areas. An Excel checklist gives deal teams a simple way to organize those requests, assign ownership, and track what has been received, reviewed, or remains outstanding.

TL;DR

  • A typical checklist organizes anywhere from 80 to 150+ items across categories like historical financials, tax compliance, and debt structure, with columns for category, document requested, a status dropdown (Not Started, In Review, Received, Waived, Complete), an assigned owner, and priority.
  • This guide covers what belongs in a financial due diligence checklist for a debt financing, the columns and formulas to use, and where a shared spreadsheet starts to struggle once documents actually begin arriving.
  • Excel works well for building the initial checklist. The friction starts when the checklist becomes part of a live financing process.
  • Termgrid’s Deal Execution module picks up where the spreadsheet stops, keeping the checklist, the documents, and lender access tied to the same deal.

What is financial due diligence

In the context of a debt financing, financial due diligence is the process a lender or its advisors use to check a borrower’s financial records, statements, and existing obligations before extending a facility. The goal is simple: confirm the borrower’s numbers are accurate, check whether it can afford the proposed debt, and catch any risks, like hidden liabilities or inconsistent reporting, before the facility closes.

This usually means looking at past financial performance, existing debt, and how much cash flow is available to support new or additional debt. It’s a narrower, more focused check than a general financial health review, aimed specifically at whether the borrower can handle the facility being discussed.

Types of financial due diligence

In a debt financing, financial due diligence is generally categorized by who is running the process and at what point in the facility’s life:

  • Lender-side due diligence is run by the party extending the facility, focused on identifying risk and validating the borrower’s claims before committing capital.
  • Borrower-side due diligence, sometimes called vendor due diligence, is run by the party seeking the financing, preparing financial information in advance to present a clean, well-organized picture and speed up the lender’s review.
  • Ongoing or amendment due diligence applies to a borrower that already has debt outstanding and is seeking an amendment, extension, or incremental facility. The scope is narrower than an initial financing review, focused on what’s changed since the last close.

The checklist itself doesn’t change dramatically between these categories, but the emphasis does. A lender reviewing a new facility weights debt schedules and cash flow coverage more heavily than a lender reviewing a routine amendment to an existing one.

Columns to include in a financial due diligence checklist

A financial due diligence checklist needs the same set of columns on every row. At minimum:

Column

What it captures

Item number

A sequential ID so each request can be referenced easily

Category or section

Groups items by financial sub-type, such as Debt, Tax, or Working Capital

Document or request name

The specific file or piece of data being asked for

Status

A fixed dropdown (Not Started, In Review, Received, Waived, Complete) rather than free text

Priority

High, medium, or low, so the most deal-critical items stand out

Assigned owner

The person responsible for chasing down or reviewing that item

Notes or red flags

Space to record discrepancies, missing data, or follow-up questions

Financial due diligence checklist

A financial due diligence checklist for a debt financing typically covers these core categories:

  • Historical financial statements. Three to five years of income statements, balance sheets, and cash flow statements, ideally audited or independently reviewed.
  • Working capital and cash flow. Accounts receivable and payable aging, inventory turnover where relevant, and recent cash flow trends or projections.
  • Existing debt and capital structure. A schedule of all outstanding loans, facilities, and contingent liabilities, including rates, maturities, and any off-balance-sheet arrangements.
  • Tax returns and compliance. National and regional tax returns for the past three to five years, along with any correspondence related to audits or disputes.
  • Internal controls and accounting policies. An overview of the accounting methods used, the systems in place, and any prior audit management letters.
  • Accounting records. General ledger, chart of accounts, trial balances, and bank reconciliations, the underlying records that support the historical financial statements above.
  • Projections. Forward-looking budgets, financial models, and the assumptions behind them, useful for checking whether future cash flow can support the proposed facility, not just past performance.

For debt financing specifically, add one more category: covenant and reporting documentation, covering any existing compliance certificates, financial covenant definitions, and reporting history if the borrower already has debt outstanding.

How to build a financial due diligence checklist in Excel

Structure the checklist as a request tracker rather than a static list. The value comes from being able to see, at a glance, what’s been requested, what’s been received, and what still needs review.

  1. Set up one row per document or item, not one row per category. A category like “historical financial statements” might expand into three or four separate line items (income statement, balance sheet, cash flow statement, audit management letters).
  2. Add a category column so items can be grouped and filtered, even though each row is a single document.
  3. Add a status column with a fixed dropdown: Not Started, In Review, Received, Waived, Complete. Avoid free text here, since consistent values are what make filtering and status reporting reliable later.
  4. Add an owner column. Assign a specific person to each item, both on the requesting side and the side responsible for chasing it down.
  5. Add a risk or flag column, commonly using a red, amber, green (RAG) system, to note items that are missing, inconsistent, or raising a concern once reviewed.
  6. Add a notes column for anything that doesn’t fit neatly into a status or flag, such as a partial document received or a clarification requested from the borrower.

Status and risk flag should be tracked separately. A document can be marked “Received” but still flagged amber if something in it raises a question, which is a distinction a single combined status column would lose.

Formulas for a financial due diligence checklist in Excel

A financial due diligence checklist for a debt financing is mostly a structured list rather than a calculation-heavy model, but a few formulas make it considerably more useful for tracking a live lender review.

Formula or ratio

How it’s calculated

What it’s for

=COUNTIF(StatusColumn, “Received”)

Counts every row marked as received

Quick progress check without counting rows by hand

Conditional formatting

Tied to the status or risk flag column

Highlights red, amber, or green automatically as documents come in

=SUMIFS(…)

Adds up a number tied to each item, filtered by category

Rolls up totals like outstanding debt by facility, straight from the checklist

Debt-to-EBITDA

Total debt ÷ EBITDA

Standard leverage measure 

Debt service coverage ratio (DSCR)

Cash flow available for debt service ÷ total debt service due

Shows whether the borrower generates enough cash to cover the facility’s payments

Fixed charge coverage ratio (FCCR)

(EBITDA − capex − taxes) ÷ (interest + scheduled principal payments)[the exact FCCR definition is set in the credit agreement]

A common covenant metric worth checking early, not just at testing time

Current ratio

Current assets ÷ current liabilities

Basic liquidity check, flags short-term cash problems regardless of overall leverage

These ratios aren’t part of the checklist itself, but calculating them as soon as the statements are received turns the checklist from a document tracker into an early warning system for whether the facility makes sense at all.

How to customize a financial due diligence checklist for different industries

A generic financial due diligence checklist works as a starting point, but the categories that matter most shift depending on the borrower’s industry and the type of facility being financed.

For asset-based lending, the checklist should weigh collateral documentation heavily: accounts receivable and inventory detail, borrowing base calculations, and any existing liens. For cash-flow or unitranche facilities, the emphasis shifts toward EBITDA quality and recurring revenue, since repayment depends on the business’s ongoing cash generation rather than a specific pool of assets.

Borrower industry shapes diligence priorities on top of that facility distinction:

Borrower industry

What a lender specifically checks

Software / technology

Recurring revenue (ARR or MRR), customer retention and churn, and any IP or licensing agreements that affect value if the lender ever needs to rely on collateral

Distribution / industrials

Equipment condition and depreciation schedules, supply chain dependencies, and the physical collateral available to secure the facility

Healthcare

Regulatory and licensing documentation, payer mix or reimbursement risk, and compliance history specific to the sector

Business / consumer services

Contract-based or recurring revenue mix, customer concentration, and margin consistency across service lines

The practical challenge is that most teams rebuild this checklist from scratch for every new deal type, rather than keeping one base checklist that adjusts by facility type and industry. 

Best practices for managing a financial due diligence checklist in Excel

  1. Assign clear ownership for every item, not just the checklist as a whole. A checklist with fifty items and no individual owners tends to stall, since nobody is specifically accountable for chasing down any single document.
  2. Use a shared, cloud-based version of the file rather than emailing copies back and forth. Once more than one person is updating status or adding notes, a single shared file (through SharePoint, Google Sheets, or similar) avoids the version conflicts that come from multiple people editing separate copies.
  3. Review the checklist on a fixed cadence, not just when something is urgently needed. A brief weekly check-in on outstanding items keeps small delays from compounding into a bottleneck right before a deadline.
  4. Keep the checklist and the actual documents separate. The checklist should track what’s requested and its status. The documents themselves belong in a secure, access-controlled location, not attached to emails or scattered across individual downloads folders.
  5. Revisit the checklist template after each deal. Note what ended up being unnecessary and what was missing, so the next deal’s checklist starts from a better baseline rather than the same static template every time.

How Termgrid keeps due diligence documents organized in one place

Termgrid is a purpose-built deal management platform for private capital markets. If a financial due diligence checklist is being run as part of a debt financing, its Deal Execution module gives the documents that checklist requests a dedicated home, through a built-in data room, instead of tracking them through spreadsheets and email attachments.

For deal teams already running their process on Termgrid, the checklist and the documents it points to live in the same place as the rest of the deal, rather than as two separate systems that have to be reconciled by hand.

Frequently asked questions

1. What is financial due diligence?

It’s the process of checking a borrower’s financial records and past performance before a loan is finalized. A lender does this to confirm the numbers are accurate and to make sure the borrower can actually afford the debt being discussed.

2. What columns should a financial due diligence checklist in Excel include?

At minimum: category, document requested, status, owner, and a risk flag. Bigger deals often add a notes column and a date column, so it’s clear when each item was asked for and when it came in.

3. How do I keep track of document status in the checklist?

Use a fixed dropdown list, like Not Started, In Review, Received, Waived, or Complete, instead of typing status in free text. This keeps the column consistent, so it’s easy to filter and count as documents come in.

4. Can Excel handle a large checklist with a lot of items?

Yes, Excel can handle as many rows as you need. The harder part is keeping one version up to date once more than one person is working on it, which is why a shared file and clear ownership matter more than the number of rows.

5. What formulas are useful in a financial due diligence checklist?

COUNTIF to count how many items have been received, conditional formatting to highlight risk flags automatically, and SUMIFS to add up numbers like total debt by facility directly from the checklist.
